Yuya Uchida (Soul Eater's Dr. Franken Stein, Naruto Shippūden's Rinji) will dub the role of Sam, while Hiroki Touchi (Trinity Blood's Abel Nightroad, Bokurano's Kokkpelli) will dub the role of Dean. Both actors dubbed these same roles for the live-action version in Japanese. [http://av.watch.impress.co.jp/docs/news/20100611_373418.html Source]
